_Tabacum Minimum_ (Gen. Em. 358.) appears to be another species, hitherto unsettled, with a branched leafy stem, a span high; leaves ovate on footstalks, opposite; and stalked acute, greenish-yellow flowers. The N. minima of Molina (Poir. in Lum. Diet. iv. 481.), is probably another species, or perhaps the same. Culture.--Tobacco thrives best in a warm, kindly rich soil, that is not subject to be over-run with weeds. In Virginia, the soil in which it thrives best is warm, light, and inclining to be sandy; and, therefore, if the plant is to be cultivated in Britain, it ought to be planted in a soil as nearly of the same kind as possible. Other kinds of soil might probably be brought to suit it, by a surface of proper manure; but we must remember, whatever manure is made use of, must be thoroughly incorporated with the soil. The best situation for a tobacco plantation is the southern declivity of a hill, rather gradual than abrupt, or a spot that is sheltered from the north winds: but at the same time it is necessary that the plants enjoy a free air; for without this they will not prosper. As tobacco is an annual plant, those who intend to cultivate it ought to be as careful as possible in the choice of the seeds; in which, however, with all their care, they may sometimes be deceived. The seed should be sown in the middle of April, or rather sooner in a forward season, in a bed prepared for this purpose, of such soil that has been already described, mixed with some warm rich manure. In a cold spring, hot beds are most eligible for that purpose; and gardeners imagine that they are always necessary: but Mr. Carver[22] tells us, that he is convinced, when the weather is not very severe, the tobacco seeds may be raised without-doors: and for this purpose gives us the following directions:
